About the Lowe Syndrome Trust
The Lowe Syndrome Trust is a UK Charity formed in June 2000 by parents of a Lowe syndrome child. The charity supports families and initiates and funds medical research into Lowe Syndrome. Lowe Syndrome is a genetic disorder that can occur with no family history, affecting boys and multiple physical and mental handicaps including cataracts in both eyes, muscle weakness (hypotonia or floppy baby syndrome), kidney problems, cysts, brittle bones, arthritis, poor growth, mental impairment with behaviour problems (autistic spectrum disorder) and epilepsy. Sadly the life expectancy for these children may be short due to the complications of the disease and the lack of funding to find a cure, however many also develop into adults and to defy any stereotypes - See Paul James who has lowe syndrome and a facilitator for The UK Learning Disability Parliament.
The objective of the charity is to initiate, fund and encourage medical research which will hopefully lead to the development of drugs to better regulate the metabolic imbalance of Lowe’s and eventually a cure. The Charity is a listed non-commercial Partner of the National Institute for Health Research (NIHR). These are organisations that award research funds as a result of open competition across England with high quality peer review; fund research that is of clear value to the NHS; and take account of Department of Health and NHS priorities and needs in their research funding strategies.

research project over 3 years or more. See Research Grants
The research initiated and funded by the charity has been of high scientific quality and has brought together many researchers from different fields that would not have studied or collaborated on studies of this rare disease without the catalyst of the Lowe Syndrome Trust. The charity has attracted serious science and scientists to try to understand what is a devastating disease for those affected by it, and their families.
What is sometimes not always appreciated outside of medical science and research is that research into one disease, especially a rare inherited disease, often reveals important insights into other diseases, and this has been particularly true of Lowe syndrome research. A ‘cure’ is still the ultimate objective, but many benefits have accrued from the research that has been funded up to now, not least in establishing a community of researchers working together and collaborating closely. The biennial scientific meetings (research symposia) organised by the Trust held at the Royal Society in London have provided an opportunity for the research funded by the rust to be presented at an open meeting and for new areas of research to be identified. Advances are being made, such that treatments to improve the lives of those affected by Lowe syndrome can and will be developed.
The Trust has funded many projects, in the UK, Europe and in the US. As an example of some of the Lowe Trust projects underway, Prof Robert Nussbaum who discovered the lowe syndrome gene created a mouse model and published a paper with Pietro DeCamilli's lab using the Nussbaum mouse models on cultured kidney tubules that clearly shows how the defect in the Lowe gene causes the lowe molecular proteinuria. The mouse model research made through the charity funding is also being used by a group led by Olivier Devuyst in Zurich Switzerland who replicated the findings. The group published a paper with Antonella DeMattei along with Martin Lowe of Manchester University UK on a cell biological function of OCRL involving lysosomes
Prof Martin Lowe's lab in Manchester University UK has made a number of important advances through three grants totalling just under £500,000 funding from the LST charity. A major breakthrough was the generation of a zebrafish model for Lowe syndrome. Having an animal model that faithfully recapitulates the symptoms seen in Lowe syndrome patients will allow researchers, Manchester included, to perform experiments to work out how the symptoms of Lowe syndrome occur i.e. to decipher the mechanisms at play. Once they know the mechanisms involved, then they can target them to devise specific drugs to correct the processes that are defective in the disease state. Importantly, by using the zebrafish model they have managed to discover defects that occur in the development of the nervous system, as well reveal for the first time how the kidney problems arise in Lowe syndrome. The latter discoveries on the kidney have led to a current LST-funded project to devise a drug screen in zebrafish. This will necessitate genetically engineering a zebrafish strain in which they can monitor kidney function in living animals. The advantage of zebrafish is that they are amenable to high throughput drug screening. Manchester hope to identify compounds that can restore kidney function in the Lowe syndrome model. These lead compounds can then be used in additional tests in other model systems prior to testing in human patients.
Martin and his team have distributed the zebrafish Lowe syndrome model to other labs around the world, so they can focus on other specific aspects of the disorder. This includes the lab of Scott Baraban at the University of California San Francisco (UCSF), who is an expert in studying seizures and epilepsy, and Dr Yang Sun at the Indian University School of Medicine, who is investigating how loss of OCRL1 causes cataracts and glaucoma. Martin will continue to distribute the fish to any labs that request them.
Other projects funded by the Trust have been at Imperial College London, University College London, Moorfield’s Eye Hospital, Dundee University, Cambridge University, Great Ormond Street Hospital, Royal Free Hospital, Institute of Child Health, Yale University (USA), University of California and Purdue University (USA).
The charity has raised awareness of Lowe syndrome and its scientific profile, and also helped with the wider recognition among doctors, the public, and our politicians, of other ‘rare diseases’
